It's a little hard to tell from your photos but it looks like your nozzle might be too close to the bed. The first layer looks thin in places and the baconing could be from the plastic being squeezed out the sides
Yeah, it can be useful to run a large 1st layer print (usually a test print) and live adjust the z axis as it's pouring the icing to get the best lines.
So as the other comments said, I also think your Noozle is too close to the bed. Do a calibration print on the middle of the bed. If you adjusted your z-offset then to a calibration print which includes the corners of your bed or just use a abl.
